摘　　要：针对温室内空间密闭、有害气体多、湿度大和温度高等条件下,人工施药会对工作人员身体健康造成很大危害的问题,设计适用于温室的自动喷雾装置。该装置的设计主要包括移动平台的设计、自动控制装置的设计和喷雾系统的引进与优化设计。利用三维软体模拟设计,并结合实际温棚空间结构和理论分析,研制具有针对性和互换改造性的自动喷雾装备,且在实际试验后进行改进优化,满足特定温室环境下对植株无人、高效自动喷药的植保作业。在温室大棚内测试了药液在葡萄叶片上的雾滴覆盖率及沉积密度,葡萄上部、中部、下部叶片正面平均分别有77.32%、60.30%、45.75%的药液覆盖率,单位面积雾滴个数平均分别为43、33、27个/cm2,表明该装置可以达到对病虫害防治的要求。Under the conditions of closed space,a lot of harmful gas,high humidity and temperature in greenhouse,artificial spray of pesticides has a big damage to personal health,so this study designed an automatic spray system for greenhouse. It included the design of mobile platform and automatic control device,introduction and optimization of spray system. This study used 3D software to simulate the design combined with actual greenhouse space structure and theoretical analysis,and produced a self-propelled sprayer device of pertinence and interchangeable transformation,which was then improved and optimized after actual experiment,realizing unmanned and efficient automatic spray under certain conditions of greenhouse. Pesticide liquid spraying coverage and deposition density on the grape leaf in greenhouse were determined,and results showed that pesticide liquid spraying coverage attached to rates of 77. 32%,60. 30%and 45. 75% at the right side of upper,central and lower parts of grape leaf on average,and the numbers of droplets per unit area were 43,33,27 respectively,which demonstrated that the automatic spray system meets the requirements of pests control in greenhouse.
